POSTING OR COPYING GUIDE FOR BOOK-KEEPERS.

SPECIFICATION forming part of Letters Patent No. 409,363, dated August 20, 1889. Application filed April 15 1889. Serial No.307,325| (No model.)

To all whom it may concern:

Be it known that I, HARRY H. LOVE,of the city of Sacramento, county of Sacramento, State. of California, have invented an Improvement in Posting or Copying Guides for Book-Keepers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a device which I call a posting or copying guide.

It consists of parallel opaque strips with transverse uniting bars and set-screws, whereby the space between the strips may be regulated, and sliding guides upon the ends of the strips for holding them in proper relative position upon the book from which the copying is to be done.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a view showing my device and its application to a book. Fig. 2 shows a portion of one of the strips.

In posting from journal or cash-book to the ledger, book-kee1 ers experience some difficulty in preventing mistakes-such as reading the name from one portion of the line and the wrong amount in the column of figuresand in copying lists of names, and in other similar work, such mistakes are apt to be made by missing names or mistaking lines.

My device is intended to prevent these errors.

It consists of two parallel opaque strips A, which are preferably made of thin rubber or These strips have clamps l3 '3 fixed upon them at opposite ends, and rods C C extend between each pair of clamps at right angles with the strips A, so as-to unite the two together. The rods have one end secured immovably to one of the strips A, and guides D are fixed to the opposite strip, through which the rods 0 slide freely, so that the two strips A may be moved to or from each other, and when the proper space has been made between the strips the rods are secured in their guides by means of setscrews E. The opaque strips A are separated so as to leave a space between them equal to the lines upon the page being copied, the remainder of the lines for a short distance above and below this one being entirely covered by the opaque strips. At one end of these strips A are fixed the guideplates G, which fit the edges of the leaves,

and the latter, abutting against the shoulders of the guides, as shown, serve to hold the strips A in a parallel position and allow them to be moved up and down in a manner similar to the movements of a T-rule upon a drawing-board. The page of the journal or other book from which the accounts or names are being copied being exposed, this device will be fitted upon either edge of the book, according to whether the left or right page is being copied from, and the space between the strips A having been adjusted to correspond with the distance between the lines on the book, it will be manifest that all but one line for a short distance on either side of the open space may be covered by the opaque plates. It will then be impossible to make an error, as all the words and figures upon that line will be copied or transferred in their proper position, with no chance of making an error by copying a portion of the line and then taking figures which may be upon a line above or below.

The device may be similarly used in copying long lists of names, and for other similar purposes.

Having thus described my invent-ion, what I claim as new, and desire to secure by Let ters Patent, is-

1. The )ostin 'orco *in 'uide consistin 'of 8 b 7 b D the parallel opaque plates with the transverse rods extending between them, guides in which said rods slide so as to allow the plates to be moved wit-h relation to each other, and setscrews whereby they are held at any given point, substantially as herein described.

2. The copying-guide consisting of the parallel opaque plates with the transverse adjusting-rods and set-screws and the hooks or guides fixed at one end of the plates, substantially as and for the purpose herein described.

In witness whereof I have hereunto set my hand.

HARRY H. LOVE.
